ROTARY ENGINE.

SPECIFICATION forming part of Letters Patent No. 535,337, dated March 5,1895.

Application filed March 10. 1894.

To all whom it may concern.-

Be it known that I, JOSEPH WEST, a citizen of the United States,residing at Galveston, in the county of Galveston and State of Texas,have invented a new and useful Rotary Engine, of which the following isa specification.

My invention relates to improvements in rotary engines by which aflanged or bladed disk is made to revolve in a steam tight ch am ber orchest. I attain this object by a revolving disk having transverseflanges 0r blades on its periphery being caused to rotate in an annularrecess in a steam tight chamber by the introduction of steam through anopening or port in one part of the circumference of said chamber andstriking the flanges or blades of the disk in the required direction inits passage to another opening or port for the exit or escape of thesteam; thus causing the disk to revolve. I have the space in the chamberbetween the entrance and exit ports of the stream, flowing in therequired direction, of greater diameter than the part where the bladesare not intended to carry steam or that part of wall of the chamber maybe suitably serrated or corrugated, thus forming a series of pockets orrecesses therein,my object being by the enlargement of steam space atthis part of chamber the better insuring of direction and the giving ofgreater pressure on the blades of the disk at that part by thesteamimpinging against stationary wall at that part of the chamber, theblades rotating closely along the general circumference of the recess ofthe chamber at other places.

Blades may be set at any angle with disk and may be scalloped out onconcave side or in place of projecting blades, hollow spaces or pocketsmay be sunk into the periphery of the disk without extending through itsfaces.

Steam may be introduced atany angle with blades and the entrance andexit ports for steam may be through either face or circumference ofcasing and at any desireddistance apart. Steam may also be superheatedor expanded in this chamber.

By using an inflammable gas in place of steam I can by means of out offin the escape conduct the gas after passing through the en- Serial No.503,148. (No model.)

gine back to the fire box and there use it as fuel.

For a more complete description reference is had to accompanying thedrawings.

Similar lettersret'er to similar parts througlb out the several views.

Figure l is a vertical section of the machine with face of casingremoved, A being steam chamber showing enlarged diameter of the recessin direction of rotationbetween entrance of steam at the portFB and itsexit at the port of escape C. At D is shown the revolving disk with itstransverse flanges or blades E thereon. F desighates the perimeter orouter casing. H shows axis or shaft of disk projecting through face ofcasing from which motion is taken.

Fig. 2 shows the same machine adapted to both forward and reversemotions, the chamber being enlarged at such places and in such positionas direction may be required, blades of disk running closely to smallercircumference of chamber between the two ports of entrance B and the twoports of exit at C direction being determined and regulated by admissionof steam through the cut off G. F shows solid parts of easing narrowingchamber to diameter of disk at that part. Figs. 3 and 4 show samemachine in position for superheating or expanding the steam in itspassage through the enlarged part of the steam chamber.

Fig. 5 shows excavations or pockets in disk in place of blades on itsperiphery also excavations in wall of chamber forming impact pockets forthe impingement of steam thereon, parts of disk being cut away to lessenfriction.

Fig. 6 is a view of that part of inner circumference or wall of chambershowing entrance and exit ports of steam and the curvilinear part ofsolid casing F narrowing the chamber to diameter of disk between the twoports of entrance as in machine adapted to forward and reverse motionsas shown in Fig. 2.

Fig. 7 represents the machine adapted to the consuming of an inflammablegas it used in the place of steam. By means of the cut off J in theescape pipe and the conduct ing pipe K the gas after passing through theengine is led to the fire .boxand there consumedas fuel, L being thesmoke or fire flue also having its vent in the escape pipe.

Among its claims to merit are: that it can be used in either a verticalor horizontal-position; its small number of parts; its simplicity ofconstruction and mode of working; its compactness, solidity anddurability. *In size it may be from the smallest toy to large enough toanswer the most powerful requirements. The larger'the diameter of thedisk and consequently more blades engaged the more steam would beutilized and greater power gained, while from a smaller disk extremevelocity could be obtained. Drawings are not made to scale. Neither areblades as shown proportionate to size of disk.

Wherever the word steam is used -it is intended to imply anyliquid orgaseous current of pressure.

Having thus-described my invention,-what I claim, and desire to secureby Letters Patout, is-

1. In a rotary engine, the combination ofa casing withinlet and exitports for steam and a bladed disk ordrum mounted therein, as hereindescribed,'the disk casingbeing provided with a steam reservoir foraccumulating and distributingsteam simultaneously to' all the diskblades encompassed in their passage through it; said reservoiror steamchamber being formed by enlarging the diameter of the recess in thecasing between inlet and exit ports in direction of rotationandbeingconcentric with the annular recess of the casing, terminating in acurved-or straight 'rear end at the inlet point, fortheimpingement'ofsteam thereon, and a gradually sloping for- Ward end to point ofexhaust; said reservoir also forming a steam channel embracing all theblades in their passage through it, the blades of the disk being adaptedto rotate in contact with the general circumference of the recessedchamber at all other places.

'2. In a rotary engine, the combination of a casing inclosing steamchambers with a bladed disk or drum mounted therein, and being adaptedto both forward and reverse motions as herein described, the casingbeing provided with two oppositely directed inlet ports for steamconducting to oppositely sloped orinclinedsteam chambersformingreservoirs for accumulating and distributing steam simultaneouslyto all the disk blades encompassed in their passage through them; saidsteam chambers 0r reservoirs being formed concentric with andlocated inthe annular recess of encompassed with steam in their passage througheither chamber or reservoir to which steam is admitted, and passingfreely through the oppositeemptyreservoir, the-direction of rotationbeing determined by admission of steam into-andthrougheither chamber.

3. In a rotary-engine,the combination of-a easing 'in'closing a steamchamber with a bladed'or bucketed drum mounted therein,

the chamber being provided with two oppositely'directed inlet ports forsteamconducting through oppositely sloped or inclined impactlpocketsformed in the wall or inner circuinferenceofthe said chamber, one setleading in-onedirection andonesetleadingin the opposite-direction toport'ot escapeor'exhaust, the disk-or'd'rum blades having their steamfaces oppositely curved or inolinedso as to engagewvit'h either set ofsteam pockets in wa'llof chamber; ad missionotstea'm througheither-inlet port-determining'the direction'of rotation.

chamber-and disk as h'ereiubeforedescribed the combination'of the cutoffin the exit or exhaust port in connection with the channel or conductingflue leading down or back to the firebox for the consuming of-gas whenan inflammable gasis used in place of steam.

5. In a rotary engine thecombination o'tthe casing, steam chamber, diskor drum,the arrangement forexpauding steam inthe engine, theout off"valve in the exhaust'and the returning channel from exhaust back to thefire box, all substantially as described and shown.
